What Is a Whole-Home Generator?

A whole-home generator is a backup power system that automatically provides electricity during an outage. Unlike portable generators, it connects directly to your home’s electrical system and runs on natural gas, propane, or diesel. Whole-home generators ensure continuous power to essential appliances and systems, keeping your home safe and comfortable during blackouts.

How Does a Whole-Home Generator Work?

When the power goes out, an automatic transfer switch detects the outage and activates the generator. The generator then supplies power to your home, restoring electricity within seconds. Once utility power is restored, the system shuts off automatically, ensuring a seamless transition.

What Are the Benefits of Installing a Whole-Home Generator?

A whole-home generator provides uninterrupted power, protecting your home from outages caused by storms, grid failures, or emergencies. It keeps essential appliances, medical devices, and heating and cooling systems running. Additionally, it increases home value and offers peace of mind, especially in areas prone to frequent power disruptions.

What Size Generator Do I Need for My Home?

The right generator size depends on the total wattage of the appliances and systems you want to power. Smaller generators (10-15kW) can run essential systems, while larger models (20-30kW or more) can power the entire home. A professional electrician can help determine the appropriate generator size based on your household’s energy needs.

What Fuel Options Are Available for Whole-Home Generators?

Whole-home generators typically run on natural gas, propane, or diesel. Natural gas provides an unlimited fuel source if your home has a gas connection, while propane is a good option for homes without gas lines. Diesel generators are often used for high-power applications but require fuel storage.

How Long Can a Whole-Home Generator Run?

A whole-home generator can run indefinitely on natural gas, as long as the fuel supply is uninterrupted. Propane or diesel models run until their fuel supply is depleted, with run times depending on tank size. Regular maintenance ensures the generator remains in good working condition for extended use.

Do Whole-Home Generators Require Maintenance?

Yes, regular maintenance is necessary to keep the generator running efficiently. Maintenance includes checking oil levels, replacing filters, testing the battery, and running the unit periodically to ensure proper function. Professional inspections help identify and fix potential issues before an outage occurs.

Should I Hire a Professional to Install a Whole-Home Generator?

Yes, whole-home generator installation involves electrical and gas connections that must meet safety codes. A licensed electrician ensures proper sizing, wiring, and integration with your electrical / electrical -panels/”>home’s electrical panel. Professional installation guarantees safe and reliable operation when you need it most.

I would like to give a huge Thank you to Roy’s and these wonderful men and the team that helped install my and my tenant’s furnace and water tanks. I originally called in because my tenants furnace died and figured to just replace them both then I woke up the next morning and my water tanks was leaking so I decided to replace both of those also since they were both the same age and old. These men were very informative, patient, polite and so were all the employees who answered the phone wherever I called. I will recommend Roy’s to all home owners I come across. Also as a landlord and working a full time job they were very cooperative with me on my schedule and with allowing someone I know to be there on my behalf to get the projects I needed done. Oh and they finance! Jamie Tulumello, Frank Aquino, Christian Fisher, and Bob Pollak.

The service provided was quick and everything was explained in a way that was easy to understand and the technician knew what he was doing. I pretended to not know anything about furnaces just to see if they told me that there was more wrong with it than there actually was. Not a chance! Honest, fast, and curtious. I highly recommend!!!

Roy’s installed a new electrical panel and re-did all the wires coming into the box. We had a dedicated plug set up for the sump pump as the precious owner had it plugged into a power strip. They added a GFI outlet in the garage and plug for the garage door opener. Precious owner had it rigged with an extension cord. We had a team of 3 men from Roy’s, Noah, Nick and Stephen who were professional and did a great job. Still more things to be done.
